Fat FIRE Calculator

Fat FIRE is early retirement without major lifestyle cuts, with a larger budget for travel, housing and discretionary spending. The target is bigger, so the plan depends on high savings and long investing. This calculator starts from a high-spending budget and shows the number you are aiming for.

How it works

Fat FIRE numbers grow quickly. With the defaults here (100,000 US dollars of annual spending, a 4% withdrawal rate and a 15% effective tax rate), the target is about 2.9 million US dollars.

This tool treats annual spending of roughly 100,000 US dollars or more as a fat budget and scales that line for other currencies. The chart shows how long accumulation takes at your monthly contribution, which is the lever that matters most.

The formula

FIRE number = annual expenses ÷ (1 − tax rate) ÷ withdrawal rate.

Who it suits

It suits high earners who can save a large share of their income for many years and who want a retirement lifestyle close to their working one.

What to watch out for

A larger portfolio means larger absolute swings in a downturn and often a higher tax bill. Planning for lower withdrawal rates, tax-efficient accounts and flexible spending is common at this level.

Frequently asked questions

How much do I need for Fat FIRE?
It depends on your spending. With the defaults here the target is about 2.9 million US dollars, and the calculator recalculates for your own expenses, tax rate and withdrawal rate.
Does Fat FIRE need a higher return?
Not necessarily. A higher monthly contribution is usually more reliable than assuming higher returns. Try both to see which changes your timeline more.
Is Fat FIRE realistic on a normal income?
It usually requires a high income, a high savings rate, or a long time horizon. Compare it with Lean and Barista FIRE to find the version that fits your situation.
